help Tarsnap FAQ

Is Tarsnap a fully self-hosted open-source backup solution?

While the client-side code is open-source, Tarsnap is actually a secure, pay-as-you-go cloud backup service rather than a fully self-hosted backend. It utilizes strong client-side encryption and deduplication before safely replicating data from your servers to an offsite location.

Can Tarsnap be used for automated disaster recovery and rapid restoration?

Yes, it provides automated backups and rapid restoration capabilities for business continuity through standard command-line utilities and cron jobs. While you cannot instantly boot a VM from it, it reliably replicates file-level data offsite for rapid recovery.

How secure is Tarsnap for replicating sensitive server data?

Tarsnap is exceptionally secure because it encrypts all your data client-side before it ever leaves your servers, ensuring not even the system administrators can access your files. The underlying service was designed by Colin Percival, the former FreeBSD Security Officer.
